Last year my trainer got me hooked on Caveman training, and I felt terrific and stronger than I had in years. Unfortunately, I let a bad mixture of personal circumstances and sub-zero temperatures get me way off track. I'm lumpier, fatter, older-looking and more depressed than I've ever felt before. The time has come to fight back with the world's most underutilized antidepressant: exercise!

Exercise elevates the mood, uplifts the spirit, helps me to think, to be creative and to dream again. It's literally a lifeline for someone like me who has suffered for years with fibromyalgia, depression and anxiety.
